MACHINE FOR CLEANING AND BBANNING TIN PLATES AND TERNE PLATES.

Specification of Letters Patent.

Application filed May 31, 1917. Serial No. 172,133. I

To all whom it may concern:

Be it known that we, JOHN HENRY STRIGK and JAMESPROPERT REES, subjects of the King of Great Britain, residing at Neath, Glamorganshire, South Wales, Great Britain,= have invented certain new and useful Improvements in Machines for Cleaning and Branning Tin Plates and Terne Plates, and of which the following is a specification.

This invention relates to improvements in machines for cleaning and branning tinplates and terneplates preparatory to the dusting of the said plates.

The present invention refers to improvements in such machines of that known type having a trough containing the cleaning material, a rotary carrying member entering the said trough and revolved by suitable means, the rotary member carrying mechanically-operated clips adapted to seize the leading end of a tinplate at one end of the trough and to draw the said plate in tension through the cleaning material in the trough and to release the said plateupon leaving the cleaning material at the opposite end of the trough, and so that if desired the plate can be received by mechanical gripping mechanism carried by a rotary member in a second trough, the plates to be-treated be ing thus held at their forward endsby the gripping mechanism and drawn or trailed through the cleaning material in the trough or troughs.

The present inventionrefers to the provision of a blade or paddle extending across the trough and being fixed to and carried by the rotary members, and located in advance and adjacent to the clips by which the leading edge of the plate treated is gripped. These paddles consist of blades fixedat any desired angle to the direction of motion, and we have found that the cleaning effect of the machine is improved by the use of such blades orpaddles, which latter carry a portion of the cleaning material in front of the plates being treated, and from the paddle the material falls and drifts loosely upon the plates. In combination with such an arrangement we generally provide springdefiecting rods, one end of each of which is rigidly fixed to the rotary carrier near the rear of the mechanical clips by which the forward end of the plate is held, and these spring rods extend rearwardly and .support the trailing portion of the plate, so resiliently holding the plate somewhat eccentric v to .7 the center about which the rotary carrier revolves and in a position in which the surface of the said plate advantageously receives the drift of the cleaning material passing from the paddle located in front of the plate; moreover upon the plate leaving one trough, the spring rods cause the free end of said plate to be delivered over the edgeof the said trough, which is convenient for the delivery of the plate on to a receiving table or into the clips of the carriers of a second trough. We will now describe a convenient form and construction of a machine with reference to the accompanying drawings by which the said invention can be carried into effect. Figure 1 is an elevation, part of which is in section, of a machine as jafore said, and Fig. 2 is a right hand sectional end viewof the same.

Referring to the drawings, an opentopped trough 1 is provided, having a rev-T o-luble shaft 2 extending through it and carried in bearings 3 in the ends of the Patented Jan. 1, 1918. v

trough, and the shaft is revolved in the direction of the arrow Fig. 1 by any suitable means, such as by a toothed wheel 4 mounted on the shaft 2, gearing with a pinion 5, 011 a shaft 6 driven by a pulley 7 from any prime mover. The interior of the trough 1 is curved after the manner indi cated in the trough onthe left hand side of i Fig. 1, hereafter referred to, the curvature being concentric with the axis of the shaft 2.

The shaft 2 has fixed upon it a plurality of skeleton disks or wheels, hereafter termed carriers 8, these carriers entering the trough 1 and being of such diameter that their peripheries are at a suitable distance from the interior surface of the trough.

Each carrier 8 carries one, or as shown a plurality, of spring clips, each of these clips consisting of a radial rod 9 suitably guided as at 10 by a pin on the carrier passing through a slot in the rod, and the rod 9 has a foot 11 which extends over thev periphery of the carrier, while a spring 12 on the rod I oftheclip acting between a nut on the rod and a lug 13 on the carrier, holds the foot 11 in contact with the periphery of the carrier; the radial rod 9 on one carrier is in line with the similarradial rods of the clips on the other carriers, and a bar 14, Figs. 1 and 2,. extends through the spaces in the carriers 8 and is fixed to each radial rod 9, and such a bar 1d we term a touch rod.

Fixed to the trough, one upon each side thereof, are two frames 15, each of which carries an adjustable cam surface 16, and also fixed within the trough there are two cam surfaces 17 one at each side thereon, these cam surfaces 16"and 17 being for the purpose of acting at proper times upon the radial rods 9 in order to distance the feet 11 of the rods 9 from the periphery of the carriers 8 to release a plate, and also to distance the radial rods 9 from the periphery of the carriers at proper times to receive a plate.

, lVith'mechanism thus far described, as the carriers 8 revolve and as one of the touch rods 14: enters the feed side of the trough, the ends of the said touch rod'let contact with the fixed cam surfaces 17, whereby the radial rods 9 connected with that particular touch rod, are moved radially outward and the feet 11 of the clip are distanced from the peripheries of the carriers, so that the tin or terneplate or plates, hereinafter termed tinplate, can be inserted between the feet 11 of the clips and the-peripl'ieries of the carriers 8, so that the tinplate is immediately gripped as soon as the ends ofthe touch rods pass away from the cam surfaces 17. Thereafter during the further revoluble motion of the carriers the tinplate is drawn through the cleaning material in the trough, in tension.

The tinplate marked 18 on the right hand side of the drawing Fig. 1, which is the feed end of the machine, is fed in between'suitable guides 19 so that the lower edge of the plate 18 rests on a stop plate 20 fixed on a rock shaft 21 to which tappet levers'22 are fixed, counterweighted at 23 and maintained in the position shown by a stop arm 2a on the shaft 21.

0n the outer carriers are laterally extending pins 25, Figs. 1 and 2, which rock the levers 22 as they pass, and tilt the stop plate 20 so that the tin plate 18 slides into the jaws of the carrier clips; The tinplate is then drawn through the cleaning material in the trough 1, and as it leaves the cleaning material the touch rod of the set of clips contacts with the cam surfaces 16 carried by the frames 15, and the'tinplate is released and can be guided onto a table or into a dusting machine as desired.

Carried from the periphery of the carriers are the blades or paddles whichform one of the features of the invention.

The paddles marked 26 in the drawings are located and fixed at'or near the peripheries of the carriers and extend parallelwith the shaft 2' thereof; each paddle comprises a plate 26 extending across the machine and fixed by brackets 27 tothe carriers, the said paddle being located in advance and adjacent to each set of clips, the purpose of these fixed to tlieface of its carrier at the rear of a clip, while the opposite free end (the rod 28 being curved) normally stands beyond the periphery of the carrier so that thetinplate, when gripped by the clips, will have its position defined by resting on the de flecting rods 28.

It will now be understood from the fore so going descrlption that a tinplate on the right hand side of the drawing Fig. 1 having been; passed into the clips, is gripped thereby at its entering endand is drawn through the trough while it is supported by the deflecting rods 28; and having so passed through the trough, the free end'of the plate is held out away from the carriers by the action of the deflecting rods 28, the plate is then released from'the clips and upon release it is free to pass away clear of the trough.

Such a machine generally consists of more than one trough, the drawing Fig. 1 showing two exactly similar troughs working in con unct1on, the shaft 2 of one trough being:

parallel with the shaft 2' of the other trough,

with the adjacent edges of the two troughs incontact, and when so arranged, the tinplates which are inserted n the spring clips at the feed end of the first trough are drawn through the cleaning material in the first trough and carried out of that material so that the lower edges of the tinplates are above the edge" of the first trough on the delivery side; and then the touch rod of a-set of spring clips, holding the plates, contacts with the cam surfaces carried by the bridgepieces and theplates are released, and guided by the ends of the spring deflect-ing rods 28 they become received by a set of similar spring clips of the second trough, which spring clips are at that moment in an open position, their touch rods contacting with the cam surfaces'fixed in the entrance end of the second trough. The plates are then drawn through the second trough and similarly delivered atthe delivery end .of the second'trough on to a bench or into a dusting machine as desired.
